savetrees – Optimise the use of each page of a LaTeX document

The goal of the save­trees pack­age is to pack as much text as pos­si­ble onto each page of a LaTeX doc­u­ment. Ad­mit­tedly, this makes the doc­u­ment far less at­trac­tive. Nev­er­the­less, save­trees is a sim­ple way to save pa­per when print­ing draft copies of a doc­u­ment. It can also be use­ful when try­ing to meet a tight page-length re­quire­ment for a con­fer­ence or jour­nal sub­mis­sion.
Most of the pack­age op­tions cover spe­cific mod­i­fi­ca­tions to type­set­ting rules, but there are also op­tions sub­tle, mod­er­ate and ex­treme op­tions for the “broad brush” ap­proach.
